I complained about the long responsetime and subsequent downtime of my interne connection for almost a month earlier.
It got fixed eventually and after very painfull and long talks to customer service. But this week, I needed to change some settings on my router, but was unable t access the web interface.
The router is supplied by the ISP, so they have access to it (without my password). Apparently, on of the techs working on my case changed my own password without informing me. He seems to have had no better imagination than to set it to 'admin'.
So, there goes my policy of choosing strong and unique passwords on my equipment because some idiot looking at a month-old ticket decides that admin is a good password for my box.
